Panels back on, and a Bimota KB4RC with a racing medium in its airbox looks exactly like one without. That is convenient while the bike is yours and less convenient afterwards, because the specification outlives the decision: the next owner inherits a filtration figure they cannot see, on a machine they will reasonably assume is standard inside. The Sprint Filter PM111S F1-85 filters to 85 microns and flows 15,000 l\/m²\/sec, where the standard P08 filters to 80 and flows 5,050. Fitting it is a considered choice. Leaving it undocumented turns that choice into someone else's blind spot.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThe racing medium: dry polyester, 85 microns of filtration, 15,000 l\/m²\/sec of flow\u003c\/li\u003e\n\u003cli\u003eSet against the standard P08 at 80 microns and 5,050 l\/m²\/sec — coarser weave here, more air, less retention\u003c\/li\u003e\n\u003cli\u003eBoth are built on roughly double the filtering surface of other performance filters\u003c\/li\u003e\n\u003cli\u003eThe absence of oil means nothing can be carried downstream onto sensors or throttle bodies\u003c\/li\u003e\n\u003cli\u003eThe swap is internal and fully reversible: standard airbox, no modification, no remap\u003c\/li\u003e\n\u003cli\u003eWashable and reusable, with two years of warranty running from the date of purchase\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWrite it down, and keep the other element\u003c\/h2\u003e\u003cp\u003eThe practical answer takes five minutes. Keep the element that came out, label it with the date and the mileage, and store it with the bike's papers; note the medium and the fitting date in the service record. A machine built in small numbers is looked at closely when it changes hands, and a documented, reversible change reads as care rather than as an unknown. It also leaves the next owner free to make the same decision for themselves — the swap back is one airbox lid and no parts.\u003c\/p\u003e\u003ch2\u003eThe case for fitting it at all\u003c\/h2\u003e\u003cp\u003eThere is one, and it is stronger here than on most road bikes. A KB4RC is ridden in short, chosen, hard sessions rather than commuted on, and wide throttle high in the rev range is the only place a flow figure of 15,000 l\/m²\/sec can be collected. The condition is the same one every racing medium carries: it belongs on an engine serviced by operating hours, opened and given fresh oil on a racing rhythm, because that is what accounts for the material an 85-micron weave lets past. Run to standard road intervals, the coarser medium is a cost without its cover, and the P08 is the element to buy instead.\u003c\/p\u003e\u003ch2\u003eCare and cleaning\u003c\/h2\u003e\u003cp\u003eCleaning it is a short list. Compressed air from the clean side, blown outwards; a wash in lukewarm water with a mild detergent when conditions have earned one; a rinse until the water runs clear; then open air, never heat and never a flame, until the element is dry. Refit it in that state. At no point in its life does the polyester get oiled. The maintenance sheet is in the Downloads tab.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eMade for the Bimota KB4RC, 2022 to 2026.
